Interchangeable Straps Slippers/Flip-flop

ABSTRACT

A Triangular metal base, sandwiched between the foot-bed and bottom sole on slippers/flip-flop, would allow an user to interchange the ‘straps’ matching their outfit, for style or taste. There would be only one foot base which could be worn with interchangeable ‘straps’. This is almost like having 2 or more pair of slippers/flip-flop for a lesser price. In addition there would be full or partial elastic band strap that would go around the upper ankle with clasps which would be attached to the Straps to give a grip to the foot by holding the foot tight to the slippers/flip-flops. As an inventor, I would manufacture this as 4 parts, triangular metal base with clasp eye, multilayered foot base, straps with claps, elastic ankle band with clasps.

Triangular Metal base with clasp-eye for slippers and flip-flops. This product contains 4 parts which are Part 1. Triangular metal base with clasp-eye, Part 2. Slipper/flip-flop sole, Part 3. Removable Straps and Part 4. Removable elastic ankle band.

Part 1. Triangular metal base with protruding metal clasp-eye. There would be 3 clasp-eyes on the Triangular metal base, i.e. one on each corner. This triangular metal would be embedded in the middle layer of a slipper/flip-flop in such a way that it would not be seen from outside.

Part 2. Slipper/flip-flop foot-bed and sole. The multi-layer slipper/flip-flop has the Triangular metal base sandwiched between foot-bed(top-layer where foot rests) and bottom sole(last-layer that touches the ground). The foot-bed has 3 covered holes (one on the toe post and two near the heel area) through which the slipper/flip-flop straps would be hooked to the protruding metal clasp-eye which is embedded under the foot bed.

Part 3. Interchangeable Straps would be having small clasps at their ends which would be hooked to the metal clasp-eyes. This way one can interchange their straps matching to their outfit, style or taste (One slipper/Flip-flop base with Interchangeable Straps).

The Interchangeable Straps are either as a single piece with 3 hands or it could be as three different pieces that could also be clasped together and then hooked to the triangular metal clasp eyes.

Part 4. Elastic ankle band—fully or partially elastic band with metal clasps that could be attached to the Straps to give a grip to the foot by holding the foot tight to the slippers/flip-flops.

The placeholder and size of the Triangular metal base and the Clasp eye would be determined while manufacturing based on the size of the foot ware.

Metal base, soles, straps would be made with materials that are widely used in this industry. The patterns and designs of straps would vary according to the trend and imagination.

Clasps and eye used would be from the market that are readily available. The Fig. attached does not show the exact clasp design that would be used.

This product would be manufactured for all the sizes that are widely followed in the United States.

As a retail seller, I would sell this product as one foot base with more than one straps so that the buyer could interchange the strap and use it.

It could be sold as one foot base with 3 pieces straps so that the buyer can now have multiple options of the straps itself.

1. The design and method of claim 1 is that the foot ware base and the strap are not attached together, but come separately. This way the user can change the strap according to their outfit and style.
 2. The design of claim 2 is that the triangular metal with protruding clasp-eye on all the corners.
 3. The design and method of claim 3 is that the triangular metal with clasp-eye would be embedded and sandwiched between the foot-bed and bottom sole.
 4. The design and method of claim 4 is that a Strap is a single three handed piece with clasps at its end.
 5. The design and method of claim 5 is that a Strap could be a disintegrated to 3 pieces with clasp-eye on one end and a clasp on the other.
 6. The design and method of claim 6 is that a partially or fully elastic band with clasps to its end could be hooked to the straps for extra grip.
